Hematite mass and molar concentrations
Equivalent molar concentration per liter About Hematite Hematite weighs 5.25 gram per cubic centimeter or 5 250 kilogram per cubic meter, i.e. density of hematite is equal to 5 250 kg/m³. In Imperial or US customary measurement system, the density is equal to 327.747 pound per cubic foot [lb/ft³], or 3.035 ounce per cubic inch [oz/inch³] .

Heamatite ore is concentrated by: Toppr
Heamatite ore is concentrated by gravity separation method. This method of concentration of the ore is based on the difference in specific gravities of the metallic ore and gangue particles. Generally metal ores are heavier than the gangue associated with them.

Hematite Wikipedia
Hematite exhibited temperature-dependent magnetic coercivity values ranging from 289 to 5,027 oersteds (23–400 kA/m). The origin of these high coercivity values has been interpreted as a consequence of the subparticle structure induced by the different particle and crystallite size growth rates at increasing annealing temperature.
